Inventor: WANSER CALVIN COOLIDGE
IPC: C09B67/18
Filed: 1976-02-11
Abstract: Metal phthalocyanine pigments of improved tinctorial strength and transparency are prepd. by (i) intimately contacting a dry crude metal phthalocyanine with 2-5 pts. of 82-86% H2SO4 per pt. pigment in the absence of shear until a pasty mass is formed, (ii) mixing the mass with a hot aq. diluent comprising water and 2-15 wt% (on pigment) of NH4OH8 (CH3)4NOH and/or NR1R2R3 (where R1 is lower alkyl or hydroxy lower alkyl; R2 and R3 are H or R1), the temp. being 75-100 degrees C, (iii) agitating at 75-100 degrees C, and (iv) recovering the pigment from the slurry. The process is used for metal phthalocyanine pigments produced by fusion synthesis, esp. for opt. halogen substd. copper phthalocyanines.

Title: Gasket for double walled pipe joint - allows heating or cooling medium in outer pipe to flow across joint
Inventor: SCHULZ WILHELM
IPC: F16L39/00
Filed: 1976-02-25
Abstract: The inner pipe (5) and outer pipe (6) are welded to a common flange (1) and form an annulus (13) for the circulation of a heating or cooling medium to control the temperature of the fluid in the pipe (5). A pair of flanges (1) are held together by clamping rings (7) and the joint is sealed by a gasket (8). The fluid in the annulus (13) flows across the joint through the holes (2) which are aligned with holes in the gasket (8). The gasket (8) has annular grooves (10) which are connected by radial slots to its outer edge. Any fluid leaking from the central pipe (5) or from the annulus (13) flows into the annular grooves (10) and into the radial slots so that neither fluid contaminates the other.

Title: Electronic circuit simulating bistable telegraph relay - has optoelectronic coupling element separating input from output circuit
Inventor: JUGEL ALFRED
IPC: H04L25/24
Filed: 1976-03-31
Abstract: Break and make contacts are produced by transistors. Input circuit receiving transmitted and rectified ac signals is isolated from the output switching circuit. Input signal pulses (E1) control an optoelectronic coupling element (K1) in accordance with a signal determining the translation sending or receiving state. Its output signals for switching on the transistor (T2) allocated to the active state becomes operative only after a time interval had elapsed, corresponding to an undistorted signal pulse. A control potential is thus applied in addition simultaneously through a timing stage controlled in accordance with output pulses. This control potential bridges at least the spacing between individual pulses, and is released when the first signal pulse becomes operative. Transistor (T1) allocated to the passave state becomes blocked at the start of the control signal.

Title: HF burglar alarm system - uses transmitter for HF signals reflected within room and received for phase amplitude comparison
Inventor: WINTZER C M DIPL ING
IPC: G01V3/12
Filed: 1976-07-07
Abstract: A h.f. detector system is used to provide protection against intruders and has high range coupled with insensitivity to disturbances. The sender-receiver within an area to be secured consists of a h.f. transmitter giving out signals from an antenna. A quartz crystal oscillator forms the basis of a signal generator producing 40,000 MHz signals. Signals reflected from a metallic component are received and are mixed with another frequency. A comparator detects changes in phase and/or amplitude and a modulating frequency is produced to interact with the sender frequency. A detector circuit within a separate area receives the signal and triggers an alarm upon intruder detection.

Title: Down-wash actuated mine for destroying low flying aircraft etc. - has reaction flow rotor generating electrical energy for setting off explosive charge
Inventor: LINSHOEFT ALFRED
IPC: F42C15/295
Filed: 1977-02-25
Abstract: The gas or air downwash from an aircraft is used for exploding concealed explosives or mines for destroying overflying helicopters, air cushion vehicles or other aircraft. The reaction air flow reaching ground initiates the explosive charges concealed in the ground. This ensures that undetected low flying aircraft which tries to avoid radar detection can be destroyed. The air stream reaching ground from the aircraft causes rotation of a bladed rotor connected to the generator shaft. This generator produces electrical energy required for setting off the explosive charge. The electrical energy activates the electromagnetic relay and the current circuit to the explosives initiator is closed.

Title: Electromagnet controlled tactile display - has braille symbols formed by axially moved pins which project beyond surface
Inventor: LIMMER LOTHAR DIPL ING
IPC: G09B21/00
Filed: 1977-05-07
Abstract: An electro-magnetically actuator forms the basis of a controlled tactile sensing unit for a Braille type system. Individual Braille type symbols are formed by a pin (3) that is moved axially to project beyond a surface (1).

Title: Work chair with tilting swivel back rest - has two section back with fixed upper part and pivoting lower part with rubber intermediate piece
Inventor: WINKELMANN PAUL
IPC: A47C7/40
Filed: 1977-05-11
Abstract: The working chair, for office, workshop or house, consists of a back rest fixed to a support.

Title: Measurement of cross modulation by two transmitters - uses two signals which are applied to tested object, and has tuner at output tuned to unmodulated carrier
Inventor: DEMMER WALTER ING GRAD
IPC: G01R29/06
Filed: 1978-06-22
Abstract: The non-modulated carrier of the useful signal is applied through a directional coupler to the tested object, and the interference carrier 100% modulated by a rectangular signal is applied to the tested object through a variable attenuator, an amplifier and the same directional coupler. The interference transmitter amplitude can be reduced so that a certain cross modulation is produced at the tested object output. The useful, interference and modulation signals amplitudes and frequencies can be measured and displayed. A receiver follows the test object and has the attenuator and a tuner with a research run system so arranged, that the tunner is automatically tuned to a practically unmodulated carrier.

Title: Mixing device - with two tubular membranes in two chambers alternately oscillated by compressed air admission
Inventor: YAMSCHIKOV VALERY SERGEEVITSCH
IPC: D06F35/00
Filed: 1978-08-25
Abstract: A liquid mixing device consists of two tubular chambers which are sepd from each other by an annular disc. Each chamber is lined with a tubular membrane, amde of elastic material, which rests at a perforated tubular support so that each membrane can be deflected inward in turn by the admission of a pressurised medium. Used in cleaning of machine parts, preparation of material to be transported in mines, mixing of pulps dispersions and degreasing in the chemical industry, wet treatment of leather and textiles. This ensures that the membranes oscillate mainly in the fundamental mode without higher harmonics. This improves the mixing of efficiency and prevents clogging of the perforations.
